Configuration on the ISATAP host
The specific configuration on the ISATAP host is related to its operating system. The following example
shows the configuration of the host running the Windows XP.
# Install IPv6.
C:\>ipv6 install
# On a Windows XP-based host, the ISATAP interface is usually interface 2. Configure the IPv4
address of the ISATAP router on the interface to complete the configuration on the host. Before doing
that, display the ISATAP interface information:
C:\>ipv6 if 2

# A link-local address (fe80::5efe:2.1.1.2) in the ISATAP format was automatically generated for the
ISATAP interface. Configure the IPv4 address of the ISATAP switch on the ISATAP interface.
